( Figs 538 View FIGURES 535–538. 535 , 549–550 View FIGURES 545–556. 545–548 , 590–595 View FIGURES 590–595. 590–592 )

Material examined. Holotype: ♂, INDONESIA, Sumatra, Jambi Province: Mt. Tujuh, footpath to Lake Mt. Tujuh , 1,500 –2,000 m (evergreen hill forest), 20 February 2000, leg. P.J. Schwendinger ( MHNG, Sum –00/15) GoogleMaps . Paratypes: 3♀, same data as holotype ( MHNG, Sum –00/15) GoogleMaps .

Diagnosis. This new species is the smallest member of the sobria -group. Males are most similar to those of M. sobria comb. nov. in possessing a round embolic base, but they have a poorly developed subterminal fold ( Fig. 590 View FIGURES 590–595. 590–592 ). Females can be distinguished by the conical spermathecae which are widest at mid-length ( Fig. 550 View FIGURES 545–556. 545–548 ).

Etymology. The specific epithet (caperatus = wrinkled) refers to the opisthosoma which is provided with many folds.

Description. Male (holotype). Total length 5.12; prosoma 2.90 long, 2.25 wide. Eye sizes and interdistances: AME 0.16, ALE 0.12, PME 0.11, PLE 0.12, AME–AME 0.8, AME–ALE 0.12, PME–PME 0.10, PME–PLE 0.38; MOQ: 0.46 long, 0.43 anterior width, 0.40 posterior width. Leg measurements: I 11.92 (2.86, 3.74, 3.00, 2.32), II 9.92 (2.49, 3.10, 2.48, 1.82), III 9.60 (2.60, 3.00, 2.48, 1.50), IV 13.08 (3.12, 3.98, 4.19, 2.18).

Coloration. Carapace chestnut-brown. Chelicerae brown. Sternum orange-brown. Legs yellowish brown except coxae yellowish. Dorsum of opisthosoma dark brown, without pattern.

Palp ( Figs 590–592 View FIGURES 590–595. 590–592 ). RTA digitiform, gradually tapered towards bluntly pointed apex. TA elongated; apicoprolateral flange sickle-shaped, apex directed posteromesad; apico-prolateral tooth triangular; subterminal ridge indistinct; basal tooth minute, terminally pointed. Embolic base spherical. Embolus blade-like, elongated.

Female (paratype). Total length 4.92; prosoma 2.82 long, 2.16 wide. Eye sizes and interdistances: AME 0.16, ALE 0.12, PME 0.10, PLE 0.11, AME–AME 0.06, AME–ALE 0.10, PME–PME 0.08, PME–PLE 0.26; MOQ: 0.40 long, 0.36 anterior width, 0.34 posterior width. Leg measurements: I 11.47 (2.75, 3.60, 2.88, 2.24), II 9.54 (2.40, 2.98, 2.38, 1.76), III 9.24 (2.52, 2.88, 2.40, 1.44), IV 13.52 (3.20, 3.90, 4.12, 2.28).

Coloration ( Fig. 538 View FIGURES 535–538. 535 ). Carapace orange-brown. Sternum yellowish brown. Chelicerae brown. Coxae whitish, other leg segment yellowish. Opisthosoma dark brown; cardiac region pale.

Genitalia ( Figs 549–550 View FIGURES 545–556. 545–548 , 593–595 View FIGURES 590–595. 590–592 ). Epigynal plate with broad transverse band, anteriorly excavated, posterior margin slightly protruding over epigastric furrow. Proximal part of spermathecae heavily sclerotized, with modified ventral swelling; distal part conical, widest at half length, internally with 3–4 coils.

Natural history. Mallinella caperata sp. nov. inhabits primary evergreen forests at relatively high altitude (1,500 –2,000 m asl).

Distribution. Known only from the type locality on Sumatra.
